D231 Dual Core TPA3223 200Wx2 High Power 2.1 Channel Digital HiFi Power Amplifier 3084 Bluetooth5.4 LDAC with Power Adapter
Description:
- D231 is a powerful 2.1-channel digital amplifier that uses two TPA3223 digital amplifier chips, with a power of 200Wx2/4ohms or 400W/2ohms, making it easy to power a 10-inch subwoofer.
- The D231 material is full of sincerity, and the RCA socket is gold-plated for greater durability. The large radiator ensures long-term stable operation, and the large capacity filtering capacitor makes the power supply more stable with lower ripple. The operational amplifier used is NE5532, which has a plug and unplug design and can be upgraded to higher-level operational amplifiers by yourself. QCC3084 is a new Bluetooth 5.4 chip that supports for LDAC, APTX LL, and uses PCM5102 for Bluetooth decoding, making Bluetooth sound quality comparable to wired transmission. The design has a delayed power on function to prevent sparks when inserting the power plug.
- D231 can not only adjust the high and low frequencies of the left and right channels, but also adapt to different speakers. You can also independently adjust the volume and low-pass frequency of the subwoofer output, which can be well connected with the speakers of the left and right channels, making the positioning of the entire sound field more natural, and the low frequency will be cleaner and more elastic.
